Result］ The new buds and petals of I.germanica was proper to be used as explant of tissue culture, with lower browning rate compared with other positions. The well situated tissue block of explant (3 mm×3 mm×3 mm) might reduce browning rate. Adding 0.1%Vc or 0.3% active carbon in medium had obvious effect on preventing tissue browning. The exogenous hormone 2 mg/L 6-BA was easy to lead to brownness turning, and 2 mg/L Kt and 2 mg/L NAA brought less effect to tissue browning. When using disinfectants of alcohol, its dipping time of 5～10 s for explant was the best, with the minimum browning rate. The culture under full illumination condition was liable to induce brownness turning, compared with other cultured conditions, the brownness turning could be restrained effectively by using imitating artificial climate condition for culture.

结果］ 鸢尾的新生芽和花瓣较适宜作组织培养的外植体，与其他部位相比褐变率较低；外植体组织块适中（3 mm×3 mm×3 mm）可降低褐变率；在培养基中加入0.1%Vc或0.3%活性炭对防止组织褐化效果明显；外源激素2 mg/L 6-BA易引发褐变，2 mg/L Kt和2 mg/L NAA对组织褐变影响不大；使用乙醇消毒剂时，对外植体浸泡时间以5～10 s为佳，褐变率最低；全光照条件培养容易诱发褐变，采用仿人工气候条件培养较其他条件培养可有效抑制褐变的发生。

It was observed that the influence of bud and its position on the healing process of grafting unions using hardwood sectioning method, and found that:(1) bud of a scion and its position to the graft unions have no influence on callusing formation of the isolation layers, and the early differentiation of cambia;(2) a scion bud closer to the grafting union would promote the formation of more compacted callus cells and the earlier formation of callus bridges;(3) conduit differentiation in grafting unions of lower-bud scions was later than that of other treatments.

利用滑动切片法对芽子有无及芽位对嫁接愈合过程的影响进行了观察，发现：(1)接芽有无及芽位对隔离层及愈伤组织形成和形成层的早期分化没有影响；(2)芽或去芽的芽位距接口近，可以促进愈伤组织的紧密连接，即愈伤组织桥的形成；(3)低位芽枝嫁接体中导管分化较晚，而其它处理导管的分化几乎是同时发生的，而且导管首先出现于愈伤组织薄壁细胞中。

CD8~+ cell is the main T lymphocyte subset in spleen, and B lymphocyte mainly is IgG~+ cell, moreover the amount of these B lymphocytes could exceed CD3~+ T lymphocyte subset after 7 days. CD8~+ cell is the main T lymphocyte subset in tonsil of appendix, and B lymphocyte is IgM~+ cell, and the amount could exceed CD3~+ T lymphocytes after 35 days. After 21 days, B lymphocytes in esophago tonsil are the main IgA~+ cells and the amount exceeds CD3~+ lymphocytes. The amount of CD4~+ lymphocytes is more than CD8+ lymphocytes.4. CD3~+、CD4~+ and CD8~+ T lymphocytes in spleen mainly distribute in periarterial lymphoid sheath. However IgM~+、IgG~+ and IgA~+ cells mainly distribute in ellipsoid periarterial lymphoid sheath and germinal center. T lymphocytes in appendix tonsil mainly distribute in middle and inferior part of mucous and the B lymphocytes mainly in middle and mucous between 4~7 days. Whereafter T, B lymphocytes equably distribute in mucous. CD4~+ cells arrange tightly and mainly occupy the central part in aggregates of T lymphocytes in esophago tonsil and CD8~+ lymphocytes mainly distribute in periphery. Meanwhile B lymphocytes encircle the periphery of aggregates of T lymphocytes. The aggregates of B lymphocytes is mainly the germinal center with lots of IgM~+、IgG~+ and IgA~+ cells. Meanwihle T lymphocytes encircle the periphery of aggregates of B lymphocytes.5. There is an intimate relationship between the development of tissue structure of peripheral immune organs and lymphcytopoiesis. The maturation of tissue structure is stimulated by the immigration of lymphocytes and the mature tissue structure provides place where lymphocytes grow mature and functionate.

脾脏在21日龄时达到稳定，食管扁桃体和盲肠扁桃体均在35日龄时达到稳定；脾脏中T淋巴细胞亚群以CD8~+细胞为主，B淋巴细胞则以IgG~+细胞为主，并在7日龄后数量超过CD3~+T淋巴细胞；盲肠扁桃体中T淋巴细胞亚群以CD8~+细胞为主，B淋巴细胞以IgM~+细胞为主，并在35日龄后数量超过CD3~+T淋巴细胞；21日龄后，食管扁桃体中B淋巴细胞以IgA~+细胞为主，数量超过CD3~+细胞，CD4~+细胞的数量多于CD8~+细胞。4、在T、B淋巴细胞组织定位方面，脾脏中CD3~+、CD4~+和CD8~+T淋巴细胞主要分布在动脉周围淋巴鞘中，而IgM~+、IgG~+和IgA~+细胞主要分布在椭球周围淋巴鞘和生发中心中；4～7日龄时，盲肠扁桃体中T淋巴细胞主要分布在粘膜固有层的中下部区域，而B淋巴细胞则主要分布在中上部区域，随后各日龄T、B淋巴细胞均匀地分布在粘膜固有层中；在食管扁桃体的T淋巴细胞聚集物中，CD4~+细胞紧密排列，主要占据中央部位，CD8~+细胞主要散布在外周，同时B淋巴细胞又环绕在整个T淋巴细胞聚集物的外周；B淋巴细胞聚集物主要为生发中心，其中存在大量IgM~+、IgG~+和IgA~+细胞，同时T淋巴细胞又环绕在整个B淋巴细胞聚集物的外周。5、外周免疫器官的组织结构发育和淋巴细胞发生之间存在密切的关系，淋巴细胞迁入淋巴器官刺激组织结构的发育成熟，同时成熟的组织结构又为淋巴细胞发育成熟并行使功能活动提供场所。
